It was about 2 months ago when I played my IV CD.
I NEVER listen to the radio by choice ( though it's not that bad in very small accidental doses ).
I either listen to my music collection or stuff on the internet these days as I really do not feel like listening the same 50 songs over and over and over again for the rest of my life. 20 years of the same 50 songs ( stopped listening to radio about 15 years ago when they killed off Pirate Radio out here ) over and over is bad enough...can't continue any farther.
Classic Rock Radio has no imagination these days and there aren't any metal stations out here.
